No, Convection does not occur in the Core.
For example, in the Sun, the convection occurs only after the Radiation zone.
In the radiation zone the energy is transported by radiation (ie, by photons).
At about 0.8 solar radius the density and temperature are not enough to
transport the energy by radiation, so convection sets in.
No, nuclear fusion does not occur in the convection zone of a star. Fusion reactions primarily take place in the core region of a star, where the temperature and pressure are high enough to sustain the nuclear reactions that power the star. The convection zone is a region of the star where heat is transported through the movement of gas, but fusion does not occur there.
The convection zone in a star like the Sun is located just beneath the photosphere. It is the layer where energy generated in the star's core is transported to the surface via convection currents, providing the energy needed for the star to shine.
Convection currents primarily occur in the Earth's mantle, which lies between the outer core and the crust. These currents are driven by the heat from the Earth's core, causing the mantle's semi-solid rock to slowly flow and circulate. This movement plays a crucial role in plate tectonics and the geological activity on the Earth's surface. While the outer core is liquid and also convecting, the convection currents that significantly influence surface processes are predominantly found in the mantle.

The convection zone is a region of the star where heat is transported through the movement of gas, but fusion does not occur there.
Convection currents occur in the mantle, which is the middle layer of the Earth. The heat generated from the core causes the molten rock in the mantle to move in a circular pattern, creating convection currents.
The convection zone in a star like the Sun is located just beneath the photosphere. It is the layer where energy generated in the star's core is transported to the surface via convection currents, providing the energy needed for the star to shine.
Convection currents occur in the atmosphere, mantle, and outer core of the Earth. In the atmosphere, convection drives weather patterns. In the mantle, it contributes to plate tectonics and the movement of Earth's lithospheric plates. In the outer core, convection generates Earth's magnetic field.
Plasticity and convection occur in the asthenosphere, which is part of the upper mantle. The asthenosphere is a semi-molten layer below the lithosphere where rock can flow slowly over long periods of time. Convection within the asthenosphere is driven by heat from the Earth's core, causing movement of material in the mantle.
Convection occurs mainly in the mantle, which is the layer beneath the Earth's crust. The heat generated by the core causes convection currents in the mantle, leading to the movement of tectonic plates.
If there is no hydrogen left at the core of star then hydrogen fusion cannot occur. What happens in the core of a star before that happens is that helium begins to fuse, and then the other elements going up the periodic table until carbon. And then if the star explodes into a supernova, traces of the higher elements are fused as well.
convection occurs in the asthenosphere, which is located under the lithosphere. the inner core heats the liquid mantle and it circles and produces plate tectonic activity.
In a star, energy from fusion moves outward from the core through radiation and convection. In the core, where fusion takes place, high-energy photons are generated and slowly diffuse outwards. In the outer layers, energy is carried by convection, where hot plasma rises and cooler plasma sinks, creating a cycle that transports energy towards the surface of the star.
Energy from the core of a star travels outward through radiation and convection. In the radiation zone, energy is transported through the emission and absorption of photons. In the convection zone, energy is carried by the movement of hot gas or plasma.
Convection currents occur in the outer core due to the heat generated by the radioactive decay of elements like uranium and thorium. This heat creates temperature differences within the outer core, causing hotter, less dense material to rise and cooler, denser material to sink, thus creating the movement of molten iron that generates the Earth's magnetic field.
